要序列化的對象的類：

[serializable]
public class person
{
private string name;
public string name
{
get
{
return name;
}
set
{
name=value;
}
}
public string sex;
public int age=31;
public course[] courses;

public person()
{
}
public person(string name)
{
name=name;
sex="男";
}
}
[serializable]
public class course
{
public string name;
[xmlignore]public string description;
public course()
{
}
public course(string name,string description)
{
name=name;
description=description;
}
} 

進行序列化及反序列化的測試類：

class test
{
//序列化
public void serialiaze()
{
person c=new person("cyj")
c.courses=new course[2];
c.courses[0]=new course("英語","交流工具")
c.courses[1]=new course("數學","自然科學")

xmlserializer xs=new xmlserializer(typeof(person));
stream stream = new filestream("c://cyj.xml", filemode.create, fileaccess.write, fileshare.readwrite);
xs.serialize(stream, c);
stream.close();
}
//反序列化
public void deserialize()
{
xmlserializer xs=new xmlserializer(typeof(person));
stream stream = new filestream("c://cyj.xml", filemode.open, fileaccess.read, fileshare.readwrite);
person p=(person)xs.deserialize(stream);
console.writeline(p.name);
console.writeline(p.age.tostring());
console.writeline(p.courses.length.tostring());
console.read();
}
}

格式化后xml的文檔內容為：
<?xml version="1.0"?>
<person xmlns:xsd=http://www.w3.org/2001/xmlschema    xmlns:xsi="http://www.w3.org/2001/xmlschema-instance">
 <sex>男</sex>
  <age>31</age>
  <courses>
    <course>
      <name>英語</name>
    </course>
    <course>
      <name>數學</name>
    </course>
  </courses>
  <name>cyj</name>
</person>
